LOOM-SHUTTLE Specification of Letters Patent.

Patented Dec. 1, 1908.

Application led November 29, 1967. Serial No. 404,217.

A have heretofore been constructed of metal and add materially to theweight of the delivery end of the shuttle. In practice I 'find that thisexcessive weight at the delivery end of the shuttle causes the shuttleto have an imperfect throw in the loom with liability of the shuttlejumping through and smashing the warp threads.

The object of my invention is to improve the construction of a loomshuttle, whereby the shuttle is provided with a light weight mechanicalthreading device adapted to fa- .Y cilitate the threading of the shuttleby hand,

without suction.

Further objects of my invention are to improve the action and appearanceand lessen the cost of manufacturing loom shuttles having hand threadingdevices.

My invention consists in the peculiar and novel construction of a loomshuttle, said invention embodying a mechanical hand threading device andthe adjacent portions ofthe shuttle and having details of construction,as will be more fully set forth hereinafter and claimed.

Figure 1 is a top plan view of the thread delivery end of a loom shuttleprovided with my improved mechanical hand threading device. Fig. 2 is aside view of Fig. l, looking at the delivery eye side of the shuttle.Fig. 3 is a longitudinal sectional view taken on line 3 3 of Fig. 2,showing the thread running through the threading device and out of thedelivery eye of the shuttle. Fig. 4 is a transverse sectional view takenon line 4 4 of Fig. 1 through the shuttle and threading device, andFigs. 5, 6 and 7 are side views of the plug member of the threadingdevice removed from the shuttle to show the construction of the same.

In the drawings, a indicates the thread delivery end of a loom shuttlebody, b the nose end portion of a bobbin in the shuttle, c a

weft thread, d my improved hand threading device, and e, f, g, and hdotted lines illustrating the successive positions the thread willassume in threading the shuttle, as shown in Fi s. 1 and 2.

The shutt e body a has a circular upper cavity 8 extending down from thetop adj acent the throat of the shuttle and merging into a slightlysmaller circular bottom cavity 9 from the bottom of which is a centralhole 10 extending down through the bottom of the shuttle, asemi-circular dished depression 11 in the top merging into the uppercircular cavity 8 on the end side of the cavity, a longitudinal slot 12connecting the upper circular cavity 8 with the throat 13 which mergesinto the usual bobbin cavity 14, a narrow longitudinal depression 15 inthe side of the shuttle, a hole 16 bored at an angle from the depression15 into and toward the end of the shuttle and on a line with the lowerportion of the upper circular cavity 8, a slit 17 cut at anapproximately corresponding angle down from the top of the shuttle tothe hole 16 and extending from the upper circular cavity 8 to theoutside of the shuttle, and a delivery eye 18 formed by a pin 19 drivenupward from the bottom through the depression 15 at the mouth of thehole 16, and a pin 20 driven downward from the to into the concavedepression 15 at an ang e to the pin 19 and slightly clearing the bottomof the depression 15, as shown in Figs. 2 and 4, otherwise the shuttlemay have the construction of any of the well known forms of loomshuttles.

The hand threading device d consists principally cf a round plug 21constructed preferably of hard wood and having a central transverse hole22, a slit 23 which extends down from the top and intersects thetransverse hole 22 at an angle and forming a downwardly-extending lip 24at the inlet end of the hole 22, as shown in Figs. 3 and 5, a shortenedside 25 the upper end 26 of which lays below the upper end of the plug,as shown in Figs. 5 and 6, a transverse hole 27 bored at an anglecorresponding to the angle of the hole 16 in the shuttle from theoutside of the plug in to a point where it intersects the transversehole 22, a transverse slit 28 cut centrally in from the side andintersecting thc transverse holes 22 and 27 and a metal wearing pin 29driven lengthwise through the plug at the intersection of the transverseoles 22 and 27, as shown in Figs. 3 and 4. The plug 21 has a driven fitin the bottom cavity 9 in the shuttle and is held in position by a in 30driven transversely through the shutt e and the lower portion of theplug, as shown in Fig. 4. The upper portion of the lug 21 and the wallof the upper cavity 8 iorm a thin annular space 31, as shown in Figs. 1,3 and 4.

In the o eration of threading a shuttle provided with my improved handthreading device, the shuttle is held in the left hand and the thread cpulled from the bobbin l) through the throat 13 and slot 12 in theshuttle. That portion of the thread in the throat 13 of the shuttle isnow depressed by the index ringer of the left hand into the throat ofthe shuttle and the thread pulled into the annular s ace 31, asindicated by the dotted line e in lllig. 1. This thread is now carriedto the right over the upper end 26 of the shortened side 25 of the plug21 through the slit 23 in the plug and through the depression 11 in thetop of the shuttle, as indicated by the dotted line f in Fig. 1. Thethread is now pulled down through the annular space 31 and the slit 17in the shuttle and through the transverse slit 28 in the plug into thetransverse holes 22 and 27 in the plug and the hole 16 in the shuttle,as indicated by the dotted line g in Fig. 1. The thread is now pulledunder the end ofthe pin 18, as indicated by the dotted line h in Fig. 2,into the delivery eye 18 of the shuttle, coinpleting the threading ofthe shuttle, as shown in full lines in Figs. 1, 2, 3 and 4. Theseoperations as explained in detail are almost instantaneously performedin one continuous movement of the hand.

By this construction I provide a loom shuttle with a light, strong anddurable hand threading device, which is not liable to break or Wear outquickly, all wear of the thread coming on the metal pins 19, 20 and 29which can be easily replaced if required, also by eliminating the use ofmetal as far as practical in the construction ofthe threading device Iconstruct a loom shuttle having practically the same weight at thedelivery end as the old form of suction shuttles and giving the sameperfect action in the loom as the older forms of shuttles.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
